A zolotnik or zolotnyk (Old East Slavic: золотни́к; abbr.: zol.) was a small unit of weight in Kievan Rus', equal to 0.1505 avoirdupois ounces, or 4.2658 grams (about 65.83 grains). Used from the 10th to 20th centuries, its name is derived from the Old East Slavic word золото (zoloto), meaning "gold". As a unit, the zolotnik was the standard for silver manufacture, much as the troy ounce is currently used for gold and other precious metals.
This unit was originally based on a coin of the same name. The zolotnik circulated in Kievan Rus' until the 11th century; it was equal in weight to the Byzantine Empire's solidus.
Relation to other units
[edit]The Rus' pound was known as the funt. There were 96 zolotniki in a pound. A smaller unit, the lot, was equal to three zolotniki. There were 96 dolya in a single zolotnik.
The zolotnik was also used to measure fineness of precious metals (gold, silver, platinum). In this case, the ratio zolotnik/funt was meant, so one zolotnik meant 1/96. For example, 14-karat (58.33%) gold was named "56-zolotnik gold" in Russia. As one karat means 1/24, one zolotnik is 1/4 karat.
91 zolotnik Russian silver has a millesimal fineness of 947.9. 88 zolotnik has a fineness of 916.6. It contains 91.66% pure silver. 84 zolotnik is the most common fineness of 875.[1]
